Python: Find the Nth member of the sequence

Python Basic - 1: Exercise-22 with Solution

Write a Python program to create a sequence where the first four members of the sequence are equal to one, and each successive term of the sequence is equal to the sum of the four previous ones. Find the Nth member of the sequence.

Sample Solution:

Python Code:

def new_seq(n):
    if n==1 or n==2 or n==3 or n==4:
        return 1
    return new_seq(n-1) + new_seq(n-2) + new_seq(n-3) + new_seq(n-4)
print(new_seq(5))
print(new_seq(6))
print(new_seq(7))

Sample Output:

4
7
13
